Postfix and Prefix Increments

Question

Was taking the lesson on increments and decrementos in C++ today and didn’t fully understand the explanation given on the difference between writing x++ or ++x. Can anyone explain it in a different way to help?

Answer 1

PapaBT it’s the other way around, prefix first increments.

Answer 2

Answer 3

Sorry - yes of cause Sergiu is right :-(

Answer 4

PapaBT Sergiu Panaite thank you both for the help, so the way i understand it now is that: if x = 5, then x++ is used, in that line x would still display as five but in the next line would be increased to six. If x = 5 and ++x is used, its increased first so that on the same line x now displays as six. Am I right with that?

Answer 5

yes, correct

Answer 6

++x
X will be incremented after the line is processed. X has the old value for processing the rest of the line.
x++
X will be incremented emidiate, and has the new value for processing the rest of the line.

If it stands alone in a line, both expressions produce the same output.
